When is the best time to water corn in the late stage (when is the last time to water corn)

In the process of corn planting, if you want to achieve high yield, you can't do without sufficient water. I believe that many farmers have heard of watering corn in the seedling stage, watering in the big bell stage, watering in the heading stage, etc. The water demand of corn in each growth stage varies.

During the growth process of corn, a lot of water is needed. When to water should be determined according to local conditions. Therefore, when to water corn for the last time should be determined according to the growth of corn, weather conditions and soil moisture content .

Because corn needs a lot of water during its growth process, we plant corn locally after the rain around May, which can reduce the number of manual watering times.

Waiting for the rainy season to come can promote growth. So which stages of corn growth require the most water?

1. Watering during the sowing period

Sufficient water and moist ground during sowing are necessary conditions for corn seedlings to germinate. Therefore, we plant corn locally around May, when there is sufficient water and the ground is moist after a heavy rain. This way, there is no need for artificial watering again and the seeds will germinate.

However, if it does not rain after sowing, artificial watering is necessary, otherwise the seeds will become moldy in the ground and fail to germinate.

2. Watering during the jointing period of corn

The jointing stage of corn is the time when corn grows most vigorously. At this time, the male and female ears begin to differentiate and require a large amount of water. If it is dry and there is no rain and the soil is dry at this time, artificial watering will be required.

3. Watering during the heading period of corn

The leaf area is large and transpiration is vigorous, which is the period in its life when corn requires the most water. Watering at this time can increase the vitality of corn pollen and facilitate pollination.

We can also extend the function of the leaves and enhance photosynthesis. Therefore, if it does not rain during this period, you must water the corn in time and do not let the corn leaves wilt.

4. Watering during the corn filling period

A large amount of water is also needed during this period to prevent premature aging and maintain photosynthesis. It can also prolong the grain filling period, increase the filling speed, and increase grain weight.

【Summarize】

Therefore, the last time you water the corn should be based on the growth of the corn.
